Abstract

A diesel Generator is equipment has functions as a power generator and electricity supply. Tanker warship is oneof the navy warships applying diesel generator Cummins KTA 38D for electricity supply when going on missionarea or at basecamp. On diesel generator system consists of 7 (seven) sub-system are coolant sub-system,seawater cooling sub-system, fuel oil sub-system, air intake and exhaust sub-system, Lub oil sub-system, Electricstarter sub-system and controlling sub-system. Due high operating hours, the potential for damage is increasing,because damage a component diesel generator. According ship damage report data, the percentage damage ofdiesel generator reach until 38.5% from total equipment damage that occurred during 2016-2022 year. Based onthat phenomena, this research will identifcation factors that cause damage and determine the components havehigh criticality in the diesel generator using the FTA (Fault Tree Analysis) to systematically explain unexpectedcausal factors that lead to failure, and the FMECA (Failure Mode Effect And Criticality Analysis) method to identifycritical components according factors have the highest critical point with calculation of the Risk Priority Number(RPN). The results of calculations and analysis using the FTA and FMECA methods, there are 6 (six) criticalcomponents with the highest RPN value in the diesel generator system, that Tube sea water component (375,4)with the risk of leaking, Impeller components (377,1) with a risk of corrosion/crack, Body Cover SW (372,0) witha risk of corrosion, Mechanical Seals (369,8) with a risk of leaking/damage, strainer (369,1) component with a riskof corrosion, Rectangular seal HE (367,9) a risk leakage and Battery (371,0) with a risk no power electric for startengine.Keywords: Diesel generator, FTA, FMECA, Critical components

Abstract

The advancement of information technology has greatly impacted various aspects of human life, including the Indonesian Navy. This progress has given rise to the concept of Cyber Warfare, which involves conducting warfare through information technology. Cyber warfare refers to actions taken by a country or international organization to attack and undermine another country's computer or information networks, typically through means like viruses or denial of service attacks.In light of these circumstances and challenges, the authors undertook an analysis to assess the readiness of the Indonesian Navy in dealing with the threat of cyber attacks, both domestically and internationally. This research employed cyber warfare threat modelling, which involved weighing and prioritizing key variables such as offensive cyber operations, cyber espionage operations, and cyber support. The objective of this study was to develop a Cyber Warfare threat model to support the responsibilities of the Indonesian Navy. Data processing for this research involved collecting relevant data from activities conducted at Satsiberal Headquarters, which was then analyzed using Fuzzy weighting. Additionally, the Dynamic System modelling method was employed to ascertain the interrelationships between variables and simulate the best alternative scenario. The results of the modellingg and simulation provided valuable insights for addressing the cyber warfare threat effectivelyKeywords: Cyber Warfare Threats, Indonesian Navy, Dynamic System.

Abstract

This research focuses on evaluating the current status of the Indonesian Navy's Minimum Essential Force (MEF) in the North Natuna Sea area. This research aims to evaluate the progress of the Indonesian Navy's Minimum Essential Force (MEF) initiative, focusing specifically on its impact within the North Natuna Sea region. Utilizing a qualitative descriptive statistical approach the research using the Delphi Method to support its analysis. The impact of achieving the MEF is dissected into three main criteria: Deterrent Effect, Bargaining Power, and Maritime Security Threat. The research identified 4 sub-factors for both Deterrent Effect and Bargaining Power, and 6 subfactors for Maritime Security Threat, all determined through consensus among expert panelists.

Abstract

ABC Hospital is a type A hospital. ABC Hospital is one of the referral centers for both TNI agencies in the eastern region and regional hospitals in Surabaya and its surroundings. For this reason, the services provided must be able to provide a level of satisfaction to the patients who seek treatment. To support this implementation, it must be supported by all parts related to the patient service process. One important part that supports the running of a good service process is the pharmaceutical installation, especially the outpatient pharmacy installation. Where the entire service process in the hospital will end at the pharmacy installation. Outpatient pharmacy installations are special because this process is carried out by the patient or their family, which is different from inpatient treatment where drugs or processes in the pharmacy installation are usually carried out by the nurse on duty in the inpatient room. The author uses arena simulation to analyze and obtain results both for existing conditions and results from experimental scenarios. Where the process begins by determining the distribution model from data observed in the field using analyzer input and then carrying out simulations, validation tests, and verification tests. Then carry out several experimental scenarios using the process analyzer. From the experimental results, we obtained better results than the existing conditions in the non-mixed (+1) and packaging (+1) scenarios, resulting in an improvement in the response variable of 15.2%.

Abstract

Malaysia, as a strategic country in the Indo-Pacific region, faces various complex maritime security challenges. In maintaining its sovereignty, Malaysia must manage threats arising from overlapping territorial claims in the South China Sea, piracy and maritime crime in the Malacca Strait, as well as geopolitical tensions between major powers such as the United States and China. Malaysia's centralized federal structure gives the federal government the authority to determine national strategic policy, including international cooperation and maritime defense. This research aims to analyze Malaysia's maritime defense strategy in facing threats in the Indo-Pacific region using game theory, maritime strategy theory, and collective security theory. This research identifies several strategies that Malaysia can take, including carrying out bilateral military exercises, joint patrols, exchanges of officers and students, as well as sharing technology and defense industry cooperation with neighboring countries such as Indonesia. Through game theory analysis, it was found that the optimal strategy for Malaysia is to carry out joint operations around the Malacca Strait and the waters bordering Indonesia, which will increase maritime security and prevent illegal activities. The research results show that a combination of bilateral military exercises and joint patrols, supported by personnel exchange programs and technological collaboration, is the most effective strategy to increase Malaysia's maritime defense capabilities. Implementation of these strategies not only strengthens diplomatic relations and synergy in developing human resources and defense technology but also creates stronger stability and security in the Indo-Pacific region. The recommendation from this research is that Malaysia and Indonesia actively implement the strategies that have been identified and continue to evaluate and adjust to ensure the sustainability and increased effectiveness of maritime defense and security cooperation in the region.

Abstract

Regional dynamics marked by an increase in submarine operations by several countries need tobe balanced with an increase in Indonesia's capabilities in underwater warfare and contribute toincreasing the country's defence system at sea. herefore, the purpose of this study is to consider thecompetitive dimension of submarine capability development on a country's deterrence effect andassess the extent of the literature review. This research is a statement that there is no instrument forassessing the capability and sustainability of submarines in an effort to increase the deterrence effectin the ALKI II region associated with the development of current dynamics so that this research isexpected to contribute to getting an instrument for assessing submarine capability and submarinedeterrence effect in the ALKI II region.
